SAW CLAMP.

Appflication filed November 14, 1923.

To all whom it may concern:

Be it known that I, JOHN K. POND, a citizen of the United States of America, and a resident of Laurinburg, county of Scotland, and State of North Carolina, have invented certain new and useful Improvements in Saw Clamps, of which the following is a full and clear specification.

, This invention relates to that type of saw clamp which is readily portable, so that the workman can. carry it from job to job easily, and the main object of the invention is to so construct the supporting structure that it may be readily collapsed into a sufficiently small space to enable it to be carried about in the tool-box of the workman, as more fully hereinafter set forth.

In the drawing Fig. 1 is a side elevation, with one of the standards in section;

ig, 2 is an edge elevation;

Fig. 3 is a plan view;

Fig. 4: is a view of the device collapsed;

Figs o, 6, 7 and 8 are views of details hereinafter described.

in the drawin 10 designates the main supporting bar ot the apparatus, which bar serves as a stationary jaw against which the sawblade 11 is clamped. The clamp consists of the aforesaid bar and a long roller 12 journaled eccentrica-lly on pivots 13 and provided with a handle 14:, so that, by throwing the handle down, the roller will be turned on the pivots until itclamps against the outer time of the saw-blade and forces the same against the main bar 10. To ease up the clamping action against the bar 10, I provide a strip of rubber 15, the same being clamped down on the top face of the bar 10 by a clamp-bar 16. The parts 10, 15, 16 and 12 are sufiiciently long to accommodate a long hand-saw, so that the filing of the saw may be completed without endwisely adjusting the saw.

The pintles 13 are journaled in depending arms 17, which are carried by brackets 18 which are formed integral with the respective ends of the long clamp-bar 16.

The main jaw or bar 10 is supported on Serial No. 674,696.

a pair of telescoping legs consisting of two upper legs 19 and two lower legs 20, these latter legs being hollow in order to telescope over the top sections 19. Set-screws 21, tapped through the top ends 01": the lower sections 20, provide for adjustment of the two leg sections with respect to each other. The upper sections are hinged to the bottom side of the jaw-bar 10, so that these top sections 19 may be swung toward the under side of the jaw-bar when the supporting structure is collapsed. The hinge-pins 22 of these hinges are made removable so that either one or both of the sections 19 may be detached from the jaw-bar when the device is collapsed, one of the sections being shown detached and collapsed in Fig. 4.

A horizontal bar brace 23'connects the legs about midway their length, this brace being provided with notches 2a in its edge to enable it to be detachably engaged down over the set-screws 21. Another pair of braces 25 is employed for bracing the legs with respect to the j aW-bar 10. These braces 25 are pivotally connected respectively to the ends of the jaw-bar and are arranged to cross each other at a point-equidistant centrally between the legs, their lower ends being provided with notches 26 to enable them to be engaged over the set-screws 21. Each of the bars 25 is provided with a series of notches 26 for purposes of adjustment. To clamp the overlapped ends of the bars 26 and 23 against the lower leg tube 20, I provide each of the set-screws with a. winged thumb-nut 27.

What I claim is:

1. In a folding saw clamp, a saw-clamping means embodying a jaw-bar, a pair of legs hinged to said bar in such manner as to swing toward each other when folded and each consisting of two telescopic sections and a set-screw for locking them in extended position, a brace-bar detachably connecting the set-screws, and a pair of crossed brace bars hingedly connecting the jaw-bar to the respective set-screws and detachably connected to the latter, for the purpose set forth.

2. A portable collapsible saw clamp embodying a clamping means having a jaW- In testimony whereof I hereunto afilx my hal a pair of telescoping legs 'hlnged to slgnature. the aw bar by removable pintles transverse- 1y arranged With respect to the jaw-bar, a dehis tachable brace-bar connecting the telescop- JOHN (X) POND- lng legs, and a pair of crossed brace-bars conmark necting the respective legs to the respective \Vitnesses:
